[root@izbp1iwt8d75s3t770dd1zz opt]# systemctl start docker
Job for docker.service failed because start of the service was attempted too often. See "systemctl status docker.service" and "journalctl -xe" for details.
To force a start use "systemctl reset-failed docker.service" followed by "systemctl start docker.service" again.

解决方案

在/etc/docker/daemon.json里面编辑{"storage-driver":"devicemapper"}
